The NHL Department of Player Safety never rests.
Donskoi left the game and didn't return after Lemieux delivered a hit to his head. The 27-year-old has 16 goals and 17 assists in 65 games during his first season with the Avalanche. He signed with Colorado as a free agent this past summer following four campaigns with the San Jose Sharks.
Lemieux, 23, has 18 points and 111 penalty minutes in 59 games this season. The son of longtime NHLer Claude Lemieux has been suspended once in his brief NHL career. He received a two-game ban for a headshot as a member of the Winnipeg Jets last season.
